Abstract
Articulated two-wheeled vehicles have front and rear frame sub-assemblies connected together by an articulated frame joint configured to enable directional and angled counter-action of front and rear wheels or skis.
Claims19
A two-wheeled vehicle comprising:
- an articulated frame assembly attachable to a frame of the two-wheeled vehicle, the frame including
- a front frame sub-assembly comprising a front wheel of the two-wheeled vehicle;
- a rear frame sub-assembly comprising a rear wheel of the two-wheeled vehicle;
- an articulated frame joint connecting the front and rear frame sub-assemblies, the articulated frame joint having a housing;
- and
- a swing bracket pivotally mounted to the housing,
- wherein the front frame sub-assembly is connected to the swing bracket,
- wherein the articulated frame assembly, when coupled to the frame, enables the rear wheel to turn in a first direction according to a turn pivot axis of the rear wheel defining a yaw angle of the rear wheel with respect to the frame of the two-wheeled vehicle, and
- wherein the first direction is opposite to a second direction associated with a roll of the front wheel according to a roll pivot axis defining a roll angle with respect to the frame.
6 more elements
An apparatus, comprising:
- an articulated frame assembly attachable to a frame of a vehicle comprising a front movement element and a rear movement element,
- wherein the articulated frame assembly is adapted to be mechanically coupled to the frame,
- wherein the articulated frame assembly, when coupled to the frame, enables the rear movement element to turn in a first direction according to a turn pivot axis of the rear movement element defining a yaw angle of the rear movement element with respect to the frame of the vehicle, and
- wherein the first direction opposite to a second direction associated with a roll of the front movement element according to a roll pivot defining a roll angle with respect to the frame.
1 more element
A vehicle, comprising:
- a frame;
- at least two wheels comprising at least a front wheel and a rear wheel connected to the frame;
- and
- an articulated frame assembly mechanically coupled to the frame enabling the rear wheel to turn in a first direction according to a turn pivot axis of the rear wheel defining a yaw angle of the rear wheel with respect to the frame of the vehicle, wherein the first direction is opposite to a second direction associated with a roll of the front wheel according to a roll pivot axis defining a roll angle with respect to the frame.
